Range, Units, Digits, Rate, and Filters
Units
Readings can be displayed using engineering (ENG) units (i.e. 1.236 M
Ω
) or scientific (SCI)
notation (i.e. 1.236E+06
Ω
). Perform the following steps to change the units setting:
1.
Press SHIFT and then DIGIT to display the present units setting (ENG or SCI).
2.
Press the RANGE
or
key to display the desired units setting.
3.
Press ENTER.
NOTE
1. The units setting can only be changed from the front panel (no remote operation).
2. Scientific notation provides more resolution on small values than engineering
units.
Digits
The DIGIT key sets display resolution for Model 6514. Display resolution can be set from
3
½
to 6
½
digits. This single global setting affects display resolution for all measurement
functions.
To set display resolution, press (and release) the DIGIT key until the desired number of digits
is displayed.
NOTE
Changing the integration rate changes display resolution, but changing display reso-
lution does not change the rate setting (see RATE for details).
